How to install Auto Headlights On/Off Sensor

These auto headlights on/off sensor is very useful, but if you do not have knowledge about headlights wiring, you might find it quite challenging to install. Thus, we would like to give our customer a general installation guide about how to install the auto headlights sensor. We will keep working on more detail about this product and hopefully we can have an installation video later on, but for now, let’s look at our step-by-step installation guide first:

1. Basically, you need to connect the headlights wires to the adapter shown below:

Blue wires are connected to Headlights
Green wires are connected to daytime running lights
Yellow is for ACC power
Red line is for constant power
Black is ground
Brown is for a remote line
White is for HIDs ( You do not need to connect these if you do not have HID )

2. Now, you need to locate your stock harness for your headlights. And it usually located under your steering wheel:

Use a wire tap to tap the necessary lines to turn on the headlights. One suggestion is to use a voltage meter and tested the terminals inside this harness to see which ones when hot when I turned on the headlights. It won’t be too hard to figure out what is the lines are for.

3. After you connect the wires to the harness, you can find a location to put your sensor. It is good to put the sensor at a place where it can sense the lights easily, for instance, on top of the dash in front of the windshield:

4. Now you are DONE! Test all feature such as the headlights, remote, daytime running lights, HIDs, etc and make sure the product works! ENJOY!
